Answer: 51

Step-by-step explanation:

Use PEMDAS. First solve inside the parentheses. You will get 43 + (4) x 2. Then, do the multiplication (4x2). You will have 43+8. And that can be simplified to 51. Hope this helps!

A round cake has a diameter of 30\text{ cm}30 cm30, start text, space, c, m, end text. Angela places the cake on a circular cake

VLD [36.1K]

Answer:

The circumference of the cake board is <u>35π cm</u>.

Step-by-step explanation:

The question is incomplete, so the complete question is below:

A round cake has a diameter of 30 cm. Angela places the cake on a circular cake board with a diameter 5 cm longer than that of the cake. What is the circumference of the cake board? Give your answer in terms of π.

Now, to find the circumference of the cake board.

As, given diameter of cake = 30 cm.

And diameter of cake board is 5 cm longer than that of the cake.

Thus, the diameter of cake board is:

$30\ cm+5\ cm=35\ cm.$

So, to find the circumference we need radius, by putting formula:

$Radius(r)=\frac{Diameter}{2}$

$Radius(r)=\frac{35}{2}$

$Radius(r)=17.5\ cm.$

Now, to get the circumference of the cake board we put formula:

$Circumference=2\pi r.$

$Circumference=2\times \pi \times 17.5$

$Circumference=35\pi \ cm.$

Therefore, the circumference of the cake board is 35π cm.

A messenger earns 2640 per year and pays tax at the rate of 10k On a naira how much tax does he pay in the year

Marta_Voda [28]

Answer:

264 naira

Step-by-step explanation:

Given that:

Amount earned per year = 2460

Rate of interest paid : 10k per naira earned

Tax paid by messenger per year :

100k = 1 naira

10k = (100/10) = 0.1 naira

Hence 0.1 naira is paid as tax on every naira earned

Total amount paid on 2640 Naira :

Amount paid per naira * total amount earned

(0.1 * 2640) = 264 naira

Which two steps could be taken to simplify the expression y/3 + 2 = 11?<br>

IRINA_888 [86]

Answer:

y = 27

Step-by-step explanation:

y/3 + 2 = 11

First subtract 2 from each side

y/3 + 2-2 = 11-2

y/3 = 9

Then multiply each side by 3

y/3 *3 = 9*3

y = 27
